Hi Eli,
Here is a simplified test case, which only assumes node.js:
* In a file C:\blackhole.js
function blackhole() {
var stream = process.openStdin();
stream.setEncoding("utf-8");
stream.on('data', function (chunk) { process.stdout.write(chunk); });
}
blackhole();
* Then from Emacs:
;; This hangs on Windows (works fine on Linux)
(let ((process (start-process "bug" nil "node" "C:/blackhole.js")))
(process-send-string process (make-string 4097 ?a)))
;; This works fine on both platforms:
(let ((process (start-process "bug" nil "node" "C:/blackhole.js")))
(dotimes (_ 25)
(process-send-string process (make-string 4096 ?a))))
Do you think you could run this example?
Thanks again for your help.
